Zero-pole cancellation and pole allocation methods were adopted to design PI regulator parameters of current inner loop and voltage external loop respectively.According to grid-connected inverter current closed-loop system＇s Bode diagram and zero-pole diagram,analysis was made to the stability of its current inner closed-loop system and experimental verification was carried out for PI parameters obtained from the method design.Experimental result shows that the double closed-loop PI regulator parameters design method is good in effect,being able to meet system design requirements.
